LEOPOLD C. SHROEDER, OF JAMESTOVVN, NEW YORK.

FEED-REGULATOR.

SPECIFICATION forming part of Letters Patent No. 324,888, dated August25, 1885.

Application filed June 11, 1885.

T 0 ctZZ whom it may concern:

Bcit known thatl, LEOPOLD O.S11ROEDER, a

citizen of the United States, residing at Jamestown, in the county ofChautauqua and State of New York, have invented'certain new and usefulImprovements in Feed-Regulators, of which the following is aspecification, reference being had therein to the accompanying drawings.

My invention relates to noiseless feed-regulators, used mainlywith'roller grinding-mills; and the object of my improvement is toprovide a laterally-yielding gate, in connection with a fcedroll, ahopper, and a receiver automatically operated by the material conductedinto the hopper.

In the accompanying drawings, Figure 1 is a perspective view of a feedregulator constructed in accordance with my invention.

Fig. 2 is a transverse vertical section of the same. Fig. 3 representsin perspective a portion of the inner hopper and its supportinggate.

In said drawings, A represents a frame in the form of a hopper, carryinga feed roller, B, mounted in bearings in the lower end thereof. Thehopper is intended to be located over the grinding or crushing rolls ofthe mill.

To regulate the amount ofmaterial escaping from the surface of theroller B, there is suspended from the outer face of the hopper A, bymeans of spring-metal straps O, a gate, 1), extending the whole lengthof the roller B. The gate carries a longitudinal tongue or strip ofmetal, 61, secured to its lower edge to bear against the side of theroller B. The gate is capable of lateral motion toward and from theroller B under the impulse of pressure or of weight against its innersurface. The straps (J are provided with slots 0, to receive the screws0", from which the gate lS suspended,

the slots permitting the latter to be adjusted and to compensate for thewear of the gatestrip d against the roller B.

To increase the efficiency and sensitiveness of this feed-regulator,there is projectinglaterally from the gate D, toward and into the hopperA, two arms, D and upon these arms is secured by means of dowels orscrews 6 the funnel E, having its walls tapering toward its lower end.This funnel is of such size as to have play-room within the hopper A andbe capable of swinginglaterally w-hen weighty substances are restingupon its walls E. The screws 0 are thus the fulcrum supporting thefunnel and its contents, and the weight of the latter, having itsfulcrum on one side of its center of gravity, operates against theresiliency of the spring-metal straps G, and forces the gate D laterallyaway from the roller B, and regulates the flow of feed of the materialescaping between this roller and the gate.

Having now fully described my invention, I claim- 1. The combination ofthe hopper A, the roller B, the gate 1), and its springstraps O with thearms D projecting within the hopper, and the funnel E, secured thereon,sub stantially as described.

2. The combination of the hopperA, the roller B in the bottom thereof,the internal funnel, E, and arms D projecting laterally therefromthrough the walls of the hopper, with the r ate secured to said arms andadjustably attached to the hopper A, substantially as and for thepurpose described.

In testimony whereof I affix my signature in presence oftwo witnesses.
